Nice additions, thank you Sinbad.
I'm glad you all find the tool useful.
As I mentioned earlier I'm open for input about what additions you find useful, as long as you can name a practical application for this.
I locally started work on a new tool called 'reorganise'. This is meant for unifying the structure of our project's mesh files. Options to change tangent semantics (tangents<->texcoords), add/strip LOD, edge list, shared vertex section and reorganising the vertex buffers with a simple syntax. But it is nowhere near ready for a commit and progress is slow, because of work load in other projects..
Btw, in the mean time Blakharaz added a new tool 'rename' that allows renaming materials, bones, animations, etc. It's working and already in the CVS.
